3y inflation

Price of the roll rise in the first year by 9%, the second year fell by 5% and in the third year increased by 3%.

Calculate the average annual increase in price of the roll.

Correct result:

p =  2.2 %

Solution:

p=100((1+9100)(15100)(1+3100)31)=2.2%p = 100(\sqrt[3]{ (1+\dfrac{ 9}{100}) \cdot (1-\dfrac{ 5}{100}) \cdot (1+\dfrac{ 3}{100})}-1) = 2.2 \%
